10/16/2025 Notice of Proposed Change to the Industrial Pretreatment Surcharge Rates by Toho Water Authority The Board of Supervisors (Board) of Tohopekaliga Water Authority (Toho), an independent special district established and created pursuant to Chapter 189, Florida Statutes, by special act of the Florida Legislature, plans to hold a meeting at 5:00 p.m. on November 19, 2025 in the Board Room of Tohos Administrative Building located at: 951 Martin Luther King Boulevard, First Floor, Kissimmee, Florida 34741. The purpose of this meeting will be to hold the public hearing for the adoption of the industrial pretreatment surcharge rates. Following the public hearing, the Board is expected to take action regarding adoption of the surcharge rate changes listed in Table 1 below. As part of Tohos ongoing efforts to ensure cost recovery and rate equity, Toho initiated an Industrial Pretreatment Surcharge Analysis to evaluate the existing surcharge structure.
